Adjustable tension type of sunshade awning

ABSTRACT

An adjustable tension type of sunshade awning comprising standing poles, standing pole bases, top poles and a tarpaulin, characterized in that each of four top poles is attached to the center joint at one end and to a standing pole at the other end so as to form the structural frame, a stretching device is provided at the end of the top pole at which the top pole is attached to the standing pole, the stretching device is provided with a latch hook, and a steel cable passing through the hemmed edge of the tarpaulin is tied on the latch hook. When a person finds the tarpaulin loses its tension, he can wrench the locking screw in the stretching device to make the sleeve pull tautly the steel cable outward in opposite direction in order to stretch the tarpaulin, and the tension of the tarpaulin can be kept by means of the self-locking action of the thread. The present utility model has the characteristics of simple structure, easy adjustment and good integration.

FIELD OF THE INVENTION

The present utility model relates to a large-sized sunshade awning foroutdoor use, particularly, to an adjustable tension type of sunshadeawning.

BACKGROUND OF THE INVENTION

In general, the structure of a large-sized sunshade awning for outdooruse is that a tarpaulin covers on a frame which stands on the ground bymeans of four standing poles, so that it has a simple and fineappearance, and the wind can blow through from all directions. Thedrawback of the structure, however, is that it is difficult to stretchthe tarpaulin on the top frame because of the manner of attaching thetarpaulin thereto and difficult to solve this problem even when thetarpaulin losses its tension, resulting in the sunshade awning as awhole losses its fine appearance while the using effect is affected.

SUMMARY OF THE INVENTION

The object of the present utility model is to provide an adjustabletension type of sunshade awning capable of keeping the tarpaulin instretching state.

The technical scheme of the present utility model for achieving itsobject is an adjustable tension type of sunshade awning, the adjustabletension type of sunshade awning comprises standing poles, standing polebases, top poles and a tarpaulin, characterized in that each of four toppoles is attached to a center joint at one end and to a standing pole atthe other end so as to form the structural frame, a stretching device isprovided at the end of the top pole which is attached to the standingpole, the stretching device is provided with a latch hook, and a steelcable passing through the hemmed edge of the tarpaulin is tied on thelatch hook.

Said stretching device comprises a stopping block, a sleeve, a pluggingend, a sliding block, and a locking screw, wherein the stopping block isfixed in the top pole with the thread formed therein, the plugging endis fixed to the outer end of the sleeve, the sleeve is clearance-fittedin the top pole with a longitudinal groove formed in its lower wall, thesliding block is fixed in the top pole and fitted to the longitudinalgroove of the sleeve, the locking screw is engaged with the thread ofthe stopping block at its inward end and attached movably to theplugging end at its outward end, a hexagon-socket is formed on theoutward end and a latch hook is formed in the plugging end.

In the structure where the locking screw can be attached movably to theplugging end, the locking screw is inserted into a hole of the pluggingend, an annular groove is formed in the locking screw, and the head of afixing bolt of the plugging end which passes through the plugging end isengaged with the annular groove.

The advantageous effect of the present utility model is that when aperson finds the tarpaulin loses its tension, he can wrench the lockingscrew in the stretching device to make the sleeve pull tautly the steelcable outward in opposite direction in order to stretch the tarpaulin,and the tension of the tarpaulin can be kept by means of theself-locking action of the thread. The present utility model has thecharacteristics of simple structure, easy adjustment and goodintegration.

DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiment(exemplary embodiments) of the invention, an example(s) of which is(are) illustrated in the accompanying drawings. Wherever possible, thesame reference numbers will be used throughout the drawings to refer tothe same or like parts.

Referring to the drawings, the significant difference of the adjustabletension type of sunshade awning of the present utility model from thesunshade awning of the prior art in which the tarpaulin is fixed bymeans of the lateral poles is that the structural frame and thetarpaulin are attached with each other in tension by means of the steelcable and the stretching device, so that the sunshade awning of thepresent utility model has the characteristics of simple structure andgood integration.

The adjustable tension type of sunshade awning comprises standing poles1, standing pole bases 2, top poles 4 and tarpaulin 5, wherein standingpole bases 2 are attached to standing poles 1, each of four top poles 4is attached to center joint 6 at one end and to standing pole 1 at theother end so as to form the structural frame, the stretching device isprovided at the end of top pole 4 at which top pole 4 is attached tostanding pole 1, the stretching device is provided with a latch hook,steel cable 14 passing through the hemmed edge of tarpaulin 5 is tied onthese latch hooks, and tarpaulin 5 is attached and fixed to thestructural frame by means of steel cable 14 and the latch hooks at thecorners.

The stretching device comprises stopping block 10, sleeve 7, pluggingend 3, sliding block 9, and locking screw 8, wherein stopping block 10is fixed in top pole 4 with the thread formed therein, plugging end 3 isfixed to the outer end of sleeve 7, sleeve 7 is clearance-fitted in toppole 4 with a longitudinal groove formed in its lower wall, slidingblock 9 is fixed in top pole 4 and fitted to the longitudinal groove ofsleeve 7, locking screw 8 is engaged with the thread of stopping block10 at its inward end and inserted into a hole of plugging end 3 at itsoutward end, an annular groove is formed in locking screw 8, the head offixing bolt 11 of plugging end which passes through plugging end 3 isengaged with the annular groove so as to form the structure wherelocking screw 8 can be attached movably to plugging end 3, ahexagon-socket is formed on the outward end of locking screw 8 and alatch hook is formed in plugging end 3.

When the stretching device is used, locking screw 8 is wrenched with thehex wrench which is mated with the hexagon-socket while the head offixing bolt 11 of plugging end which passes through plugging end 3 isengaged with the annular groove, stopping block 10 is fixed to top pole4 and can not be moved, and sliding block 9 is fixed to top pole 4 andfitted to the longitudinal groove, therefore, sleeve 7 can not rotate,and locking screw 8 is forced to move outwardly, making sleeve 7 withplugging end 3 move outwardly also, so that tarpaulin 5 is stretched bysteel cable 14 which is tied on the latch hook of plugging end andpulled tautly in opposite direction so as to achieve the final object.The adjustment scope for stretching tarpaulin 5 depends on the length ofthe longitudinal groove in the lower wall of sleeve 7.

While the preferred embodiment of the present utility model is describedhereinbefore, it is apparent for those skilled in the art to makevariations and modifications without departure from the principle of thepresent utility model, and the variations and modifications still belongto the scope of the present utility model for which protection issought.
